如何使用python获取最新创建的文件名而不是文件夹名？

Question

The following code works well and gives me the require output with the file path.

import glob
import os

list_of_files = glob.glob('/path/to/folder/*')
latest_file = max(list_of_files, key=os.path.getctime)
print latest_file

But if the file is created then it will give the file path but if the folder is created then it will give the folder path. Whereas I was expecting only the file and not the folder created in a specific folder.

Kindly, suggest what I should do to get only the latest created file path and not the latest created folder path.

Answer 1

you can use something like this using lambdas

filelist = os.listdir(os.getcwd())
filelist = filter(lambda x: not os.path.isdir(x), filelist)
newest = max(filelist, key=lambda x: os.stat(x).st_mtime)

If you are importing os already, then you don't need any other modules to achieve this. os has a module called path which handles path related functions.

To check if a path is directory or a file, you can check os.path.isfile('/path/here') which will return a boolean true or false depending on if the passed parameter is a file or not

Try this:

import glob
import os

def check_file_status(path,direc=None):
    if direc==None:
        list_of_files = glob.glob(path)
        latest_file = max(list_of_files, key=os.path.getctime)
        return latest_file
    else:
        new_path = direc+'/*'
        list_of_files = glob.glob(new_path)
        latest_file = max(list_of_files, key=os.path.getctime)
        return latest_file

if __name__ =="__main__":

    path = '/your path to file/*'
    if os.path.isfile(check_file_status(path)):
            print(latest_file)

    elif os.path.isdir(check_file_status(path)):
            add_into_path = check_file_status(path)
            print(check_file_status(path,add_into_path))
